Valid rack entry | Bradley Smoker PLC-5 guide

Communicating with Extended-Local I/O	8-11

For this Field	A Scan List Contains
Scan rack address	1-17 octal (PLC-5/40L controllers)
	1-27 octal (PLC-5/60L controllers)

Starting group number	0, 2, 4, or 6

Chassis size	4-slot, 8-slot, 12-slot, 16-slot

Backplane addressing	1-slot, 2-slot, or 1/2-slot

Range	Automatically calculated based upon rack
	address, starting module group and chassis size.
	An asterisk (*) after a range indicates the last
	valid rack entry.

Keep the following limitations in mind when creating/modifying your scan list:

•A scan list only can have 16 entries because only 16 adapters can be on channel 2.

•The automatic configuration always displays the actual hardware configuration, except for chassis that have their global inhibit bit set. In this case, that global bit overrides the automatic configuration. You must first clear the global inhibit bits for all chassis on the channel, and then use the autoconfigure function.

•Clear global inhibit bits by using the controller status status screen.

•A scan list can have a maximum of 16 chassis. Entries cannot be repeated on the scan list.
